3 Connect Hardware
Plug the TSL2521 Daughterboard into the Controller board (Figure 1). Always use ESD procedures
when handling the EVM.
Using the enclosed USB cable, plug the micro-B connector into the EVM module. Using the other end
of the cable, plug the USB A-connector into a USB port on the computer.
When the USB cable is connected, the green LED should light on power up to indicate that power is
being received via the USB interface, and the controller board processor is running. If the green LED
does not light, check the USB cable connections; unplug the USB cable and try again. If the green
LED still does not light, check the PC for USB error messages.
